As an example,the 3 D paleostructure of the boundary between Middle Eogene an...

作为实例，我们重建了汤原断陷纪中期白垩系顶界维古构造。

The basin tectonic model: it is intermont basin during late Jurassic to early Cretaceous, developed into faulted-lacustrine basin in Eogene, and evolved into depression in Neogene and Quaternary.

“盆地”构造模式为：从晚侏罗到白垩纪末期山间“盆地”开始、展到纪断陷湖盆、再演化为晚纪及四纪地陷阶段。

In eastern China, transgression occured periodically during Eogene, and formed specially paleobio-cenosis,mineral association and rock type.

在中国东部纪沉积演化过程中曾周期性地生过海侵,从而形成了具有海相特征岩石类型、古生物组合。
